TO ALL WHOM IT MAY CONCERN: I

Be it known that I, BENJAMIN RANDALL, of Adams, in the county of Jefi'erson, and State of New York,

have invented a new and improved Sulky-Harrow; and I do hereby declare that the following is a full, clear,

and exact description thereof, which will enablethose skilled in the art to make and use the same, reference being had tothe accompanying drawings, formingpart of this specification.

This invention relates to a new and improvedmanner of combining a harrow with .a. 'sulky or ridingattachment, and is an improvement on a similar device for which Letters Patent were granted to me, hearing.

date 12th November, 1867. v l The object of thepresent invention is to simplify the previously-patented machine,'and, at the same time,

attain all its-advantages with a higher or more elevated draught, which causes the harrow to work steadier, or w more evenly in contact with the grounda veryimportant feature in the operation of the machine.

In the accompanying sheet of drawings I Figure 1 is a side view of my invention, a portion being in section.

Figure 2, a plan or top view of the same.

Similar lettersbf'reference indicate corresponding parts. 7

A represents a sulky, which may, if desired, have aseed-distributing apparatus attached to it. B B represent the thills of the sulky, the front ends of which meet in a point, and have a curved elastic bar, 0, attached to them, the shape of which is shown clearly in fig. 1.

The harrow is composed of two equal parts, 1) D, connected together by hinges or joints, a a; Thisharrow is provided with the usual or any proper teeth, and is about of-square fornn'and has a diagonal position relatively withthe sulky, as shown clearly in fig. 2.

On the front part of the harrow thereis secured an upright, E, which may be constructed of metal, and t has the draught-hook 6 attached to it. The front end of the elastic bar G-is also attached'to the upper end of this upright, E, by a screw-bolt, c.

The whifflertree is connected to the draught-hook b, and it will be seen that the upright, E, gives the whiflietree an elevated position above the harrow, so that the front endof the latter will not be liable to be pulled up from the ground as the device is drawn along. This is an important feature of the invention, as it insures the harrow performing uniform work. The 'harrow, also, in consequencelof having the elastic bar 0 resting. upon its front part, is kept down, so as to elfectually resist an upward movement of the barrow under the draughtmovement of the machine. I

An adjustable-caster wheel, cl, is attached to the front end of the harrow, which prevents the barrow from running too deep. I

This elevation of the whifiie-tree, in connection with the pressure of the sulky op the front part of the barrow, admits of the horse or a team being hitched much nearer than they otherwise could be, without pulling the harrow up from the ground, and causing the liarrow to operate very imperfectly. I

In the original invention, the pressure of the sulky is on a spring at the centre of the harrow, and the whifiie-tree is attached close down to tihe harrow, and consequently, if long traces be not employed, the harrow has a tendency to rise under the draught-movement or pull of, the horse or team. This difiiculty is 'obviated by the present invention. I

Having thus fully described my invention, what I claim therein as new, and desire to secure by Letters Patent of the United States, is-

1'. The connecting of the sulky to the burrow by means of elastic bar, 0, attached 'to the front ends of the thills B B, and to an upright,'E on the front part of-theharrow, substantially as shown and described.

2. The upright, E, attached to the front end of, the harrow, and having the whifile-tree and elastic bar C connected to it, substantially as and for thepurpose specified.-

3. The adjustable caster 0?, attached to the front end of the barrow, when the same is constructed and arranged so as to operate substantially as described. i

4- The combination of the upright, E, and draught-hook b, when the same are constructed and arranged so as to operate substantially as described. v

5. Attaching the rope H to the barrow, sllbstantially as and for the purposespecified. In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

B. RANDALL. Witnesses:
